RIP Nicholas Courtney
RIP Brigadier Lethbridge-Stewart

Nicholas Courtney played Brigadier Sir Alistair Gordon Lethbridge-Stewart in UNIT, Doctor Who. Nicholas Courtney passed away on 22 February 2011.
Nicholas’ potrayal of the frequently exasperated Brigadier (who wouldn’t get exasperated with the Doctor?) was so long-running and beloved that the Brigadier has his own Wikipedia page.
Lest we forget.
